Analyzing my WCing temp change results, your thoughts please.

post #1 of 16
Thread Starter 
I am to the point in my build (build log found here) that I can run my system and check temps. The in detail temp change post can be found here. To sum it up, I got a change of 23c off my GPU temps, however only a change of 4c off my CPU temps.

In my opinion, my CPU temps were not bad to begin with. I had a beast of a cooler (nh-d14). Yet, I can't help but wonder what my temps would be like with a better pump. I have 4 more gentle typhoons coming to go in the push position on both rads, but I really don't think it will make the outstanding change in my CPU temps I was hoping for. I know how to mount a CPU cooler and this one was super easy to mount, so I doubt the lack of change is from my TIM/mounting technique. In my opinion, my temps are what is to be expected from an i7 950 at 4ghz or the pump is struggling. What leads me to think it is the former is the change I got in my GPU temps.

What are your opinions?

I agree, with your setup, the pump is lacking I think.

To be honest the Noctua cooler is a stonking good cooler , and the drop off the GPU cards is amazeing,

To get more of a drop off the CPU id have to seperate loops, I kinda say that alot in thease forums seems to be common but the GPU's will be passing heat through the loop, and onto the CPU

And the Work on the Case and loop is amazeing the GPU blocks are the SEX honestly lovly blocks

2 loops won't help your temps... Imo, you were expecting to much out of it. I7's almost always run on the high side of 50c+ so to he honest your temps are fine even with 1.28 volts.

It's most likely not the pump. The pump is actually pretty strong and GPU waterblocks/radiators don't add much restriction to your loop anyways. You should have around 1.0 GPM of flow, which is more than fine. Increasing your flow rates beyond 1.0 GPM doesn't help temperatures anyways.

I think your problem is either a bad mount on your CPU or a blockage in one of your blocks. The GPU temperatures seem a little high as well, I would expect <45C load on both the GPUs even after overclocking. Did you flush out the radiators before installing them? If you didn't you almost certainly have gunk floating around your loop that is now getting trapped in your blocks and restricting flow.

Think your pump will do fine found a post were a guys runs cpu, 3x gpu and mobo block off your pump

You would need to run 2 seperate loops if you want really good cpu temps
post #7 of 16
God, why is everyone recommending dual loops? His problems aren't caused by his GPUs, they are cause by something else that's either prevent the radiator from being effective or restricting flow.

Also, @ OP

Did you make sure you got the inlet and outlet positioned correctly on the CPU block?

Duh cause the gpu's when under load dump **** loads of heat making his already 50c temps even higher when they are under load as well TWO LOOPS would solve it is it worth the added cost probably not

While two GPUs do add quite a lot of heat into his loop, his total of 5x120mm of radiator power will easily handle it all.

Yes, I am sure.

I did flush. Took 5 gallons of distilled water, but every component is flushed.

It is my understanding that all temps in a loop eventually even out, thus dual loops serve no purpose. For example, in a balanced loop, the temps in the GPU are approximately the same as the temps in the rads.

Here is the XSPC x20 750 pump going crazy with flow in benchmark test -


I uploaded a (horrible) video to youtube showing the flow in my reservoir as best I could -


and another, its sideways but you can get the idea-


In both of my videos you can see the complete lack of turbulence that is seen in the benchmark test. Am i looking too much into this or is the pump lacking?
